Holy hell with a kit

Sears freespirit.

So it's my first ped, but I've had decent enough luck with it so far.

Putting a 64 polini kit/reed valves/compression head on it. Have a Del 16.16 SHA carb (82 jet) and an estoril pipe on it. The day before the kit arrived I was having some trouble kicking it over, but eventually it behaved and I just chaulked up to the fact that it's a janky ass ped.

So I installed my kit. Lubed the shit out of all of it, kept it clean and tight. I didn't do any radius boring or anything because I'm not so sure of myself about that kind of thing yet. Got it all installed and it won't kick over. I dropped some gas into to cylinder and it does fire, but for some reason I can't get the thing run. Took the carb apart- still nothing. Tried a different carb- nope. Took the whole kit off and put the stock cylinder and head back on and nada. I have spark... What the hell is going on...

Re: Holy hell with a kit

crappy gaskets? compression?

Re: Holy hell with a kit

I thought of that... Shouldn't be the issue though... New gaskets all around...

Everything was tight...

Re: Holy hell with a kit

is your gas line on ? and your on off switch, i only say this cause i have done that tried for a week could not figure it out :P

Re: Holy hell with a kit

Yeah... I even checked the petcock to make sure all was well with it. I took apart the carb apart so many times I probably poured off about a quart of gas today... And yeah... my peds wiring is so stripped down... yeah... trust me I was getting spark. I even checked the plug by grounding it to the block and pedaling it... It was working...

Re: Holy hell with a kit

is a gas line clogged ? and spray some carb cleaner where any 2 surfaces meet any way just for kicks and giggles (sorry about that :P)

Re: Holy hell with a kit

timing?my bike sheared the keyway so it sparked but the timing was in the next galaxy

Re: Holy hell with a kit

How do go about adjusting the timing?

Re: Holy hell with a kit

i agree with zeke- had that happen on my minarelli- take your magneto off to make positive that woodruff key is in good shape and is holding everything in place.

Re: Holy hell with a kit

rotating that plate underneath your magneto where your points live.Two flathead screws on slots.What I was refering to was the keyway the flywheel (magneto) rides on. To check this you need a piston stop and a flywheel puller. It's alot easier than it sounds

Re: Holy hell with a kit

Alright... I'll see what I can do about this timing issue. So far I've been able to tinker most of this stuff out as i go. Hopefully this won't be beyond me.

Re: Holy hell with a kit

yeah I bought a Batavus that had a sheared woodruff key... crazy thing was so far off timing it ran backwards half the time.

Re: Holy hell with a kit

Fuel, spark, compression.

When you take apart your carb, have you been checking to make sure the jet is squeaky clean?

Do you have spark when you hold the sparkplug against the cylinder head and kick it over?

Can you pedal it with the starting clutch engaged at all?

Re: Holy hell with a kit

Yes fuel was good. Checked the line, petcock etc...

Compression was there, though I took it apart and put it back together and I'm thinking it may have a leak this time, but I can go over it again.

My carb is almost brand new and the jet is gorgeous...

I did hold the plug to the block and kick it over and it did spark...

It did seem like it did want to start, but maybe my compression is off or my timing is off??

Le sigh...

Re: Holy hell with a kit

If you've got consistent spark, and the cylinder is wet after you try to start several times then pop the head, then try unscrewing the spark plug, spraying a little starting fluid in the cylinder, replacing the plug, and giving it a try. If that doesn't work, I'd look at timing.

Re: Holy hell with a kit

did u put the piston in the wrong way.. ie upside down or exhuast side on the intake side... common 1st time polini instal mistake.

Re: Holy hell with a kit

🇮🇹💦 Of the Loin /

Re: Holy hell with a kit
