yeah thanks. Man do those rev 440's ever pack a punch! 100HP! Wonder who sold their soul to the devil for that.

Hello,
Hope someone might have any ideas. Picked it up used couple weeks back and it started great. Towed it home, started great again and drove it to the back yard. Sat for 1 week. Cannot start now. I have done the following:
'Thumb' compression check seems OK, verified getting spark, cleaned the carbs today, put new plugs in. Also has 3/4 tank of year old gas with some stabil.
Fuel on/off is definately ON. Plugs are wet.

30-40 pulls with choke on full already.

Any suggestions?

Thanks,
Sean

It sounds like it's totally flooded. try leaving it a night, or starting it with the throttle at full. See if that does it

if you have spark its probably flooded,easy on the choke
