LOL - don't get too excited yet it's still not running!

Needs electrics sorted still to find a fault, exhaust, accel cable and a couple of other fiddly bits once the trailer is registered.

Thanks for the comments though - I am pretty excited myself!

The Trailer is registered! That was a lot less painful than I imagined, the only thing I didn't realise and is Mongrel's tip of the week: Keep all your receipts! They wanted receipts for the axles, springs, steel, wheels, everything just to prove I wasn't rebirthing someone else's hard work. Only weighed in at 270kg which was pretty good - with Aluminium tray and keeping it light that was the plan. Now I can add my toolbox, fuel carrier and anything else I feel like...

Off on holidays for most of a month so once I get back it's load up the Piranha to get the electrics and exhaust sorted - I am getting excited now!

Cheers

I pushed it out of the shed so it could get some sun last weekend! :wink:

Have been a little busy but starting to gear up again slowly, lots of fiddly bits still to do so I have to make a list again and cross them off as I go...

Decided I needed a little shed therapy today, so I finished wiring up the fuel pump. Mounted a 16 gauge plate and put on an external switch and light as well as wiring in to the ignition, thought it might be safer this way:

Image

Fuel pump is working and filling up Gravity tank but is noisy as hell even after rubber mounting, might have to check and see if it's an issue with the pump - vibrations and clack clack through the frame sure to drive me nuts!

Image

Now this is working it is almost right to go and get the spark issues checked out - all comments welcome!

Motor doesn't run yet with spark issues so technically it should work but can't say for sure yet...

yeh no probs what spark probs r u having or havnt u worked that out yet? i am hopefully gonna do a motor test run in the nexts week or two just waiting on new cable for my leads. i had it running before but it wouldnt idle so i have pull the carbs recently and removed the jets and fully cleaned tha carby with carby cleaner. i found all of my idle jets were partially blocked to fully blocked. my mains looked ok. also found stale fuel in the bowls so wasnt fun cleaning it.

Surge Tank is the go for sure,

Mongrel, Pump should not be doing that!

Mongrel, that’s the way Facet pumps are........noisy.
The also love to fail at the most inopportune moment, normally caused by vibration.
Facet pumps don't like buggies, or is it buggies don't like Facet pumps?

Pumping to a gravity header tank may be the way to go.

Hi Tony,

This is a low pressure pump which pumps to a gravity feed pump in this system.

Cheers

The longest buggy thread ever finally as an update...

I have spark! And even kick when I spray 'Start ya bastard' into the carby... My mate came over yesterday for 3 hours and fixed what the last 'mate' supposedly fixed so we are good to go finally.

I do have a question about my carbies, I have fuel leaking out from extra outlets - not sure what they are so looking for some professional help:

It looks like maybe a return line? Not sure though. Anyone who has one please comment!

Thanks

Those carbies look to be abit on the shitty side, a good clean would help, ive not read your thread, if you havent already cleaned them, a full stripdown and clean the jets out is a MUST.

With help from the friendly people at Pirtek I have made up the missing hose although still not entirely sure where it goes... Anyone??

I am getting a lot of popping and farting but no firing as yet with fuel still leaking from the carbies a little. I had soaked them in carby cleaner and everything seems to be moving well, they were drained and dried after each start attempt over the years... Flames from the pipes worry me a little but I am still excited to finally have spark. Thinking cap is on to troubleshoot issues and all comments gratefully appreciated!

Cheers
