New Starter. Sounds funky

[LocknFestBug]

There was nothing wrong with the starter that came with my 68 Bug, but I was going on a long trip and since I replaced the battery and alternator, I decided to change the starter out too.
I bought a new Bosch starter online and the first thing I noticed is it was smaller than what I remember VW starters being. The mounting flange was good, but the motor itself seemed really small.
I changed it out and it definetely started faster than usual, but I didn't like the sound it made. Not really a bad grinding noise, but just different. I have only had it in two weeks, but yesterday when I started it, it seemed to run on untill I revved the engine slightly.
I love the fact that it is a Bosch, but I'm not confident in it and am thinking of putting the old one back in....
Do I need to shim it? Something just don't sound quite right with it.

Autostick self supporting style starter?

This one?

They do sound slightly different.

No, you don't shim VW starters. (small block chevys do.)

I'd say its normal.

I also have that starter, it def spins that engine fast. Mine will barely do a a spin before it starts. This may sound strange but maybe you're used to the old starter and holding the key to start a bit too long now for the new starter? I had to think about that in my case. Mr D has heard and seen this on my bug.

If your starter was the same in the pic (the pic has the bronze bushing on the snout of the gear) you should definitely install the new bushing that should have come in the box with the starter. You'll need to remove the starter to get to the bushing. While you have it out, look for obvious signs of wear. Lube the inside of the bushing and the tip of the starter gear before reinstalling.

If the starter body was smaller (newer more efficient design) you should expect a different sound/tone to the starter. After you replace the bushing, as long as the sound is not a grinding sound, I'd not worry about it.

The starter in your ad is not a Bosch. Nowhere did I see the name Boash in the ad. Also, your new starter maybbe smaller compared to your old one because your old one was the larger, heavier auto-stick starter.

Does he have to pull the engine to replace the bushing?

Supposedly, there is a tool to tap in and replace the bushing from the transmission side. But ... I just paid a little extra and bought a new Bosch auto-stick. No bushing to mess with.

I've decided to go ahead and replace the starter with a new Bosch starter that doesn't require the bushing, and sell the one I have in it now.

Thanks for all the input everyone.

I removed the starter and installed a new self supporting Bosch SR15N autostick starter. and now it starts immediately!
New starter, new alternator, new battery, new ground strap, what a difference!

Now on to replacing the mechanical fuel pump with an electric.

From my pov, there is nothing WRONG with an electric fuel pump. The benefits you quote are reasons to want an electric pump over mechanical. You seem to have bought a good quality pump (Carter vs. generic) which is one of the big problems with switching from mechanical to electric.

There are a few things that electric fuel pump owners need to watch closely (some you have already taken into consideration):

The use of a relay that shuts off the electric fuel pump when the engine stops (or after a strong shock to the car). This will prevent fuel being pumped from the tank after a crash creating a dangerous fire hazard situation.

Cheap generic fuel pumps have less consistent pressures. Buy a good quality pump.

Fuel pressure regulator. Most electric fuel pumps for carbs were meant for larger engines that expected 5-10psi of fuel pressure. The stock Solex carbs are rated for 2-5psi of fuel pressure and favor just 2-3psi. Without fuel pressure regulation (regulator) many electric pumps will flood the carb and overpower the Solex inlet valve/float.

Electric pumps tend to be "pusher" pumps. This means they need to be installed up front below the tank.

Electric pumps may be more sensitive to dirt in the fuel. Install a good fuel filter upstream of the pump.
