At last, after much designing and building we have a Recovery trailer to carry an Austin Champ and completed a successful test run in and around Seymour. A long time coming, however, to meet Victorian registration requirements it takes a lot of engineering to tow anything with a gross weight over 2 tonnes.

Tows well and handles very well, the Humber pulled it well, handles the flat well and holds its speed to most inclines. Small troubles with the B60 rotor button kicking in occasionally (Governed). A learning experience to drive with weight towed behind but all good and very happy.

Cheers,

Dave.

hi Dave,
Good work, looks a nice outfit. regarding the rotor arm governer kicking in, do what the soldiers used to do with the Ferrets, wedge a matchstick in. You are not going to over rev intentionally, just the odd occasion when you want the umph uphill I suspect.

Hi Dave and a great looking rig you have there, I towed my champ from Hervey Bay to Corowa last month with my Patrol 4.2 Turbo and it was a journey and a half but well worth it. My trailer is a big one and well able to take the weight, I did get stopped on the QLD/NSW border by the Cops and Transport Nazi's but they give me the all clear. Glad the 1 Tonner is going well, I bumped into Rich Couts-Smith while there. Hope to do 2020 Champ Camp.

After a little bit of head scratching i have overcome the miss/hesitation in the B60. First i dismantled the spark plugs and cleaned the carbon deposit from the ceramic insulator. After i have raised the compression ratio from 6.4 to 7.1 with a motor overall it is pushing carbon past the internal seal. Took it for a drive a little better but not fixed. Second, i removed the screw connector in the coil high tension lead and spotted a lot of carbon dust in the thread and around the internal contact - blew out with air, cleaned and refitted, test drive, better again but not fixed. Finally i rechecked the spark plug gap as it is opened out as i have electronic ignition fitted. Readjusted gap by eye making it slightly smaller. Test drove and i have a new truck - all fixed.

I believe it was a series of symptoms causing the problem with the main culprit being to wide a plug gap. Under pressure and torque i think that the spark was partially extinguished across the larger gap by the increased compression.

Well, that's my theory for the problem.

Dave.

Well done Dave,

Could have turned into an issue that you'd chase for days instead of hours.

Could you post some more pictures of your beast. One of the engine bay would be nice to have a look at.

Simple folk like me like pictures...
