I got the Blaster out today and started it up with:
33.0 pilot
290 main
and the Vito's needle is I believe in the 4th position....haven't checked in a while.
Well I went out to start it and it started right up and it idled VERY high. Not revving to the moon, but it consistently stayed at a high idle. Air screw adjustments had absolutely no affect on it. Now I just did a leakdown test and the engine is air tight. It held 7psi for well over 15min and didn't even budge.
So I took the carb off and had some smoke rolling out of the engine and it just kind of smelled a little hot. So not chancing it I just threw in:
320 main
left the needle at 4th spot
but changed out the 33.0 for the stock 32.5 pilot....just out of curiosity.
Started it up and it idled a lot lower and appropriately. Went out for a ride and the main performance was worse, but it still ran ok.....it didn't flood out like I thought it would. I have some videos of it that I might post if it brings any aid.
I'm going to take it outside city limits with new plugs obviously to get it "dialed" in, but just taking for a casual stroll through the yard, what's the deal with the idle and revs hanging? Could it be a carb boot leak? I would think if the 33 pilot was too rich it would just flood it out as opposed to idling high(unless extra air was coming through). Reed issue? :-/
