Passage to the act, E85 test

[SixK]

Well, I just took the plunge too ...

R21 Carbu:
- 1/3 ethanol
- 2/3 petrol

The engine seems to cash without flinching yet.
It remains to be seen how it will start cold and hold over time.

I felt a slight drop in power, so I don't think I could climb higher without changes ...

If you are sure you always have an E85 pump on your journey, change it on the diameter of the nozzle + change the ignition advance as the two forumors who did it on their 205, so you can run 100% ethanol.

I have an old 21 R1986 nevada GTS carbu that I don't use much. I would run it 85% E100, but no pump in my circulation area.

perso aillant already made the changes on my 309 I bandage that sixk is right to proceed like that because going direct to ethanol the engine is not likely to appreciate it it would be necessary if it face and worse maybe its gigleurs we may not need to open.

sixk see how much% ethanol you can go up, if before reaching 100% your ratatouille car, see if with the settings advance to the ignition, idle fuel and richness it does it and only if that is not enough begins to open your nozzle by 0.05 bit, that is to say if your nozzle is for example 110 you do your calculation to add 22% it makes you 135 but you do not open it immediately at 135 you go there gradually, you open at 115 then if not enough 120 then 125 etc etc

on my advice a friend a month had a nozzle 110 to open it only 125 instead of 135 and it was enough the 0.10 mm difference would have been for him unnecessary overconsumption

22% (or as certain says 1.5 times on the surface) is a maximum and not a minimum

a+

for cold start I have start at approx. -4 / -5 this winter it is true that starting with these temperatures is a little more difficult but it starts anyway, and actually by the temperatures of these last day c is no problem. for your engine it has nothing to do with mine made that I had 2 R21 I know your mill well

Do you think it could work on the engine of the R21 GTS? not sure we can settle the advance? ... I replaced the carburetor which remained blocked (butterfly) by one of R19 found in a breakage; it works very well with this new carb, but good gasoline should not be driven too much because of consumption and gasoline prices, as it is a station wagon I just use it to transport stuff and tow a trailer for DIY.

[vassago076]

of course it will work with your engine and without problem

Thank you vassago076 !!

When they have installed an E85 pump, I will ask for pipes.

Have a good trip with your 309 and keep us informed about the engine, how it performs over time.

[vassago076]

OK no problem

for my engine I had no problem until then but if it ever happened I would post without waiting

For the moment the R21 (240 km) cash without flinching, no starting problem, no holes in acceleration, just a slight loss of power, but nothing annoying since I never pull on the engine .. .
I think I can reach 50% without changes, but I'm still not too keen on fueling a lean mixture.
The last time I disassembled my candles (before ethanol), I had the 2 central candles already very white and the 2 black external candles ...
So I must have a fuel imbalance already at the base
Perhaps this is the normal setting on a double body?

I would have to find what size of nozzle has an R21 TL 1,7l. It's not the price it costs a sprinkler

Otherwise near my house 0,740 Cts of euro per liter, it makes you want to always put more! ;)

slt for your problem of candle c is odd it would rather make me bandage to an air intake some by because it would be necessary that you go several carb to have a fuel imbalance and there you only have to try to deepen the problem before continuing your try

little idea to offer you when your engine starts trying to pour a can of gasoline on the gasket of the intake pipe (dimension cylinder head and not dimension carburetor) at the spark plugs which are white, if your engine speed changes is that you have an air intake at this place, finally it's an idea like any other I may be wrong

I think there is a poor seal on the intake pipe, it should be disassembled and put a new seal or redo it with special loctite.

Is the engine not rattooing a little at idle?

I had a problem on mine, there was play in the axis of the carburetor butterfly + poor sealing of the intake pipe. Since I put a new carburetor of breakage (without play) and remakes the joint of the admission, it starts and turns nickel. I look forward to the 1st E85 pump.

The intake and the exhaust being superimposed, the heat of the exhaust ends up deforming the carburetor (design error gentlemen engineers !!).
