One cylinder is not firing for some reason (either fuel or spark). By pulling the plug and trying to start it you remove all the resistance to try and compress the air on the non firing cylinder, thus the engine can start and idle with only one cylinder firing.

To answer my own question, The stock timing with the MSD is set to turn on the indicator light right at TDC. I found a sheared woodruff key when I took mine apart.

I recently had sheared the woodruff key and even with the timing wayyyy out it would still backfire and sputter.

I been having an issue with backfiring recently and it looks like I may have sheared the flywheel key. I have the light on the ignition box that indicates when the spark plugs fire. I rotated the engine by hand it and the static timing appears to fire at about 10-15 degrees ADTC which seem wrong...

Yeah thats what I started to think to, which is making it a nightmare to know what to order. I spoke to a shop and the guy said he vaguely remembers the early model 750s had a 18mm coupler diamter, then they switch to 20mm in late model small pins. Can anyone verify this?

I know this topic has be raised plenty of times and I have looked through all the threads, however I did not find the exact answer I was looking for. On my particular engine it has 12 bolts on the intake side. It has a 20mm diameter coupler on the crank (which SBT says is a big pin), however...

There is no markings on it at all, it almost looks like its used to increase the intake velocity going into the crankcase.

Also can anyone tell me if this is a stock part or what it is? Who ever had the engine before me had the reeds sitting in this. One of them looks to be in ok shape, the other looks very deteriorated.

Thanks for the info. I was looking around and might just go with the SBT built engine, has anyone had any good or bad things to say about it? http://www.shopsbt.com/kaw-1994-750sx/P40-20.html They said it comes with 2 year warranty that covers everything from water in the engine to blown...

Cannibal, Thanks for all the heads up, I will call to confirm with atlantic jet sport. Do you know of a say a hood retrofit that I could buy and install? I will take some pictures when I get home from work this afternoon and maybe you could give me a few pointers. The ski does currently have a...

I know that the pin diameter for these pistons is 20mm which I got off the weisco website after googling the part number stamped on the piston. http://www.wiseco.com/ProductDetail.aspx?AppID=&ItemID=813M08200&ModelYear=&ModelID= So a small pin 82mm should work just fine I would think. I am...

Do they not have a number you can call? I cant seem to find one.

Awesome thanks for the link, Weisco wanted $130 a piston. I will go this route since the walls are ok.

Thats the plan, I need atleast a piston as well. But I am going to get 2 new ones and run a quick hone through the cylinder. The issue is SBT doesnt have +2mm pistons they only carry up to +1.5mm, it looks like I will have to go through wiesco for them. Also when I pulled off the hood one of...

Hey guys, I bought this thing and had it 3 weekends, every weekend I got about an hour on it before something broke ending my weekend. I finally got it running great and was practicing some turn subs just like I watched on the videos posted on here a bunch and this is what happened. Upon...
