Re: wvpr 204 wont run
First thing to try would be to see what the condition of the sparkplug is....
If its dry its a fuel delivery problem .....Wet a spark issue
I would start by removing the carb from engine,,
removing the petcock from the carb,,,
disassemble the petcock,,,
fill void with JB Weld,,
let cure 24 hours,,
drill straight through petcock body from top to bottom with a 13/64" drillbit...........
reinstall the petcock
totally clean it out
reassemble carb with modded petcock,, new 1/4' fuellines,,new 1/4" high flow fuelfilter and inline 1/4" fuel shutoff made by stens.........
remove the fueltank and wash it out,,,drill the output hole open first to remove any casting slag that slows/hinders proper flow,,,fresh 93 octane mixed to 40:1 is optimal fueltype and premix ratio amount
remove the reed plate and make sure not to rip gaskets...if you do rip the gaskets new ones can be made by purchasing rolled rubber fiber gasket material and cutting a new set with an exacto blade and hole puncher..........
Make sure the reeds are sealing properly and reassemble carefully not to cause any airleaks and such
Install reedplate and intake back onto engine making sure to check the plastic stock intake for leaks.........
put in a new NGK sparkplug # BM6A gapped to .030"
remove the pullstarter,,check the flywheel,pickup for rust and oxidation,,clean both up and regap to .020",,then reinstall pullstarter...............
After that your bike should startup and run great if it has proper spark and compression aswell...................good luck
