First - thanks to all who helped me get this beast running last year. It ran great all summer but as the weather got colder it became very hard to start, to the point where I just let it sit all winter - had snowmobiles to ride anyway!

So, into the shop I go today to give it a try. After tons of cranking and adding a battery pack to the brand new monster marine battery I already have in it, I got it running. BUT, it only fired after I let it sit for a while.

Sequence...
1. crank crank crank for several minutes. no start.
2. let it sit for 10 minutes to have starter cool.
3. crank again and nearly instant start up.


If it was a gas engine I'd say it was flooded. But I'm not familiar with LP enough to know if that's a thing?

Note, last year I took the mixer apart and cleaned it but did not replace any parts. Also, never rebuild the cut off or regulator as they seemed to work fine. Wondering if it may be something in there?

Any ideas would be welcome.
