Hey guys, just picked up a99 700MM, when cold it won't start and seems to be a fuel delivery issue because I give it a little shot of carb cleaner in one hole and pull it, it fires up no problem, when warmed up it takes 2-3 pulls. I just rejetted and cleaned the carbs, floats set, and carbs synced-they were off. Wondering if you guys think this is a fuel pump issue or is it something else? It also seems hard pulling, but it is -18 out, idk.

plugs, plug caps? make sure your getting a nice blue spark cold and no rust on the fly wheel, to start. i would look at the reeds, maybe a few chipped petals.

If it was electrical, why dies it pip right off with carb spray down one hole? I checked reeds when I had carbs out and they are perfect

make sure the choke is actually pulling the plungers all the way open

Did you physically pull the reed cages out? or just look in at them with the carbs off? Also, what did you rejet the carbs to when you had them apart. How's compression on the motor? All orfices in the carbs sprayed and blown out? pilots etc? These carbs are pretty tempermental. Check your choke plungers like Staggs said.

I took the reeds out completely and inspected them. I also took carbs completely apart and made sure everything was clean. I rejetted from 10k'to sea level specs. The only thing I didn't pull was the float valves. I'm going to pull the recoil and see if I can see anything out of the ordinary and clean it up, carbs to check fuel pump/impulse line/needle/seats.
