Hi! Id like to say thanks to SnowAndMud community for all the help Ive received with all my newbie questions. Having a resource like this helps those of us who dont know what we're doing the confidence to try.

Just finished a rebuild on a 2012 ProRMK. It started, no weird vibrations but the dash did not come on. I noticed RPM was a bit low. Then she sputtered out. I restarted a few times more or less the same thing. If I gave her gas she would start to build rpm but then die instantly. If I let her idle she would sputter out. I usually run the non ethanol resistor so I tried the ethanol one since I premixed my fuel in the tank. Everything was starting to get really smokey in the garage so I havent dug too deep yet. Where should I start??

Did you put the fuel lines into the correct holes? I know they can go into either one. Have you connected all the electrical plugs in correctly? Double check each plug.

i labelled the fuel lines prior to disconnecting so im pretty sure those are right. but i didnt prime the fuel line thinking itll prime itself during the first few pulls. Is it possible theres air in the fuel lines?

I believe it was a set of fouled plugs from me leaving a bit of oil on top the piston. Seems fine now.

I think that connector is for the digital wrench.

What pistons did you end up going with?

i went with wiseco pistons. figured the lighter weight pistons would be good for reliability. I know they need to be warmed up properly
