Maxxam 150 2r Will not start
Hey Ya'll, I have a Maxxam 150 2r that will not start. I have replaced the stator, CDI and spark plug and finally have spark. Unfortunately, even with spark it will not start, I cleaned the carb and all jets are clear but
still I don't believe fuel is getting into the cylinder. How can I test the choke? Or would this have anything to do with it? Thanks in advance!!
An update.. I adjusted the valves and installed a clear fuel filter and I can now see a problem. No fuel is going through the fuel filter, fuel comes out of the tank just fine when the line is not connected to the carburator. What could be the problem with the
carburator?? Thanks
Sounds like the float valve or the fuel inlet passage may be blocked. If you haven't already, running compressed air through the fuel inlet barb on the carburetor after dissembling the float linkage. Travis • Buggy Depot • Enthusiast owned and operated since 2005
Tried that during a complete break down cleaning of the carb. Decided to just buy a new one since it didn't fix my problem. Hopefully be here tomorrow!
So I replaced the carb, starter, starter solenoid and can now get buggy to fire up but I
can't keep it running, after it dies I crank it over to get it to fire up but it won't. I pulled the plug and it's dry once again. I just can't seem to keep fuel flowing. The plug is also black, not fouled out but burnt. Any suggestions? Seems I am getting closer to getting this thing running. Update on new parts: starter and solenoid, variator pulley (fins were broken off)

Still can't get it to fire up even with starting fluid, although it does sound differently for the first second. Here is one more thing I tried, I reconnected the wires to the brake master cylinder to see if maybe there was something with that. I can turn lights on with key in on position but when I try to start it nothing happens. Not sure where to go from here. I do know fuel still is not getting into engine since the plug remains dry. My next option is to buy new carb since I once again took it apart and made sure jets were clear. Anyone know how many turns out the air/fuel needle needs to be? I tried one and a half and two and a half turns out.. its not your carb (it may be dirty) but if it didnt start with starting fluid, its the carb isnt the problem yet Ok, what about maybe a weak spark? Is there a way to test this? I have replaced stator, cdi, coil, and plug but there is still the possibility I'm sure. | ||

You said the variator turns so that means that the engine pistons/valves are turning. You said the valves are fully adjusted so that should be good. I will make a list of what it could be From most likley to least likley, this is what i perform when i work in the shop with your conditions 1. Spark plug, ignition coil is not tight or corroded/loose connections Now heres how to test this stuff
out. /\/\/\/\/\/\/\/\ Let me know- remember PM | ||

I even went back through and tested each of the old components again and found it was actually only the CDI that was bad. | ||

Battery is brand new and charged, I keep battery charger on it while cranking. Positive and negative wires are not hot so no short. So a run
down: Think that's it. | ||

I removed it and just touched wires together. Although my carb was bad too. I replaced it and finally got the buggy to start today! but.. it was short lived, I let the engine run for about 15 minutes and then the engine sounded like it was starving for fuel and died. I tried to start it up again and nothing. Pulled spark plug to check spark and it was dry! Brand new carb stopped working apparently. Going to try and get it replaced since its only a week old! I will update once I get it all running again. Thanks for all your help! Update: So I found another problem, rubber seal in gas cap was pretty much gone. Took gas gap off riding mower (temporarily) and now my plug is wet again. I was able to fire it up briefly then it died and I haven't been able to get it to start since. I am still getting fuel and spark. Rechecked valves and played with the air/fuel valve a little. | ||
