Whizzer wont start

[DieselTech]

It's got oil and fuel, I know it's got compression I hear when i hear it when I turn it over, no reason it shouldn't be getting spark but how can I check for that? Also when I've had it going previously it makes a distinct sound when I have the decompression lever engaged, I'm not hearing that when trying to start it recently when I pedal the bike up, I'm sure this is because of the belt slipping. As for the rear wheel I have it as far back as it'll go

Could there be a possibility that your decompression valve is stuck? Or possibly the intake or exhaust valve stuck? Since you not hearing that distinct sound.

If it turns over easily without using the compression release lever You got no compression

I haven't started my whizzer in a while since I live on the east coast and it gets pretty cold here so I've stored it for the winter and now I'm trying to get it back up and running but I am not able to get it started, im 95% sure it's a belt tension issue, this is biggest issue i've had with it. The rear belt keeps slipping on the clutch pulley and im not sure why, the belt is new and i've tried adjusting it but nothing seems to work. I've been told I could move the engine forward, would that work? Any help is greatly appreciated View attachment 187114View attachment 187115

The clutch spring looks shot, it's all stretched out That's probably why your belts are loose, The clutch is too low
Contact Paul @ www.whizzercruzzerparts.com and order a clutch new spring.
BUT.....
Looking at your air filter and also the valve cover/compression release I'm pretty sure you got a 1999-2004 WC-1
Sorry, those have problems with the valve seats coming loose and could be part of your problems.
You said it sounded different just trying to start it, Yep sounds like a loose valve seat, Pull the head and inspect the valve seats.
The only way to fix that is to upgrade the engine with a NE-5 style top end kit

Paul can sell you what you need to upgrade your engine to a NE-5 style top end or maybe you should just buy a new engine

Sorry once again the WC-1 valve seats came loose within the first 500 miles The seats were pressed in place, It's a common way to install valve seats But the WC-1 engine temperatures were too high and the seats came loose, the cooling fins on the cyl were too short

Whizzer USA solution was to offer the upgraded NE-5 top end kit, The seats were cast in place when the cyl was cast and the cooling fins were made taller, But of course with the NE-5 the head, exhaust manifold, intake manifold, carb, air filter, and valve cover, are different so it requires a NE-5 top end kit, but with all that work to do Maybe a new NE-5 style engine is for you

Vuit, how are you coming along?
It does sound like your exhaust valve is stuck open, you can remove your valve tappet cover and check to see if it's moving up and down.

I can help walk you through with the slip clutch.

Vuit, this is a wc-1 cylinder. You might still have the restrictor inside your intake, you can pull off your carb and take a look. This cylinder had almost 500 miles on it, look and see there was no leaking between the head and cylinder, valve seats working well, don't believe your top end isn't any good.
Can you tell me what you would like to do with your motorbike.
I have extra parts, are you willing to learn how to use them.I have WC-1's , Ne's,and Se's

I know Wrench mentioned they had a restrictor plate in them. I did not realize they had them choked down that bad! That's crazy, looks like about a 1/2" hole only.
