|SergheiS||Turns out that the choke cable doesn't have enough slack, and was forcing the choke to stay open. I had to disconnect the choke cable in order to let it close fully. It runs fine & starts warm no problem now, just cold starts require me to hold the mechanism by hand until it warms up enough...|

|Paulywog||I don't use any throttle when hot either,I just touch or bump the start button hot or cold with choke.|

My issue seems to be tracing back to the fact that the choke won't fully close, leading more gas into the cylinder. I have a thread opened about that.

|Goofyfoot2001||So now that you mention it, when I replaced my petcock with the tw200, I don't think I had any hot start issues again. It ran better too. So maybe that vacuum is affected by the heat and that changes pressure etc. ? It's a $15 something to try.|

Mine never will hot start with the throttle open, even have to choke it sometimes after just a few minutes being parked. If I open the throttle at all it just backfires.
Sounds like a mix of some flooding maybe, with an air leak. Check the carb boot clamps (air leak) and check the petcock vacuum line to make sure there's no gas in it (flooding front cylinder).
AGM battery makes for better starts, and the Two-Wire Mod can help with hot starts also. Both help with voltage.

|SergheiS||Another question, how much movement should the choke plungers on the carburetor have? I can put my choke lever all the way forward/choke off position, but I can push the plunger in more with my hand on the carburetor. Is this normal?|

|SergheiS||It'll occasionally make a (small?) pop, I try to let it sit between longer cranks to avoid flooding|

does it backfire loudly when trying to start? if so,look into an AGM battery.also look up the pick-up coil mod
